Pray would be a skill meant for Enchanters. It would work thusly: Pray has a chance of reducing all damage to 0. Max chance would be, say, 15%. If you have Pray trained, you cannot attack or cast any DD. All you can do is sit and pray.

Flame on. I just thought enchanters should have a skill, but since they can concentrate their exp so much, it shouldn't be gamebreaking or anything.
